Summary: | The utility model relates to a liquid nitrogen adding device, which is characterized in that a slender flow guide pipe can extend into a smaller opening of a liquid nitrogen tank to pour liquid nitrogen from a filter cover, and then the liquid nitrogen can be guided into the liquid nitrogen tank through a conical funnel and finally through the flow guide pipe. The flow guide pipe extends into theliquid nitrogen tank, so that liquid nitrogen leakage can be effectively avoided. Moreover, when liquid nitrogen flows into the flow guide cover from the filter cavity, the liquid nitrogen needs to pass through the filter screen, so that impurities in the liquid nitrogen can be separated and cannot enter the liquid nitrogen tank. Once more impurities are attached to the filter screen, the filter cover can be drawn out of the flow guide cover, and the impurities on the filter screen can be poured out. At the moment, the relative positions of the flow guide cover and the liquid nitrogen tank donot need to be changed, an |
